Q: Apple Cinema Display 27" No signal at all to custom built PC/hackintosh! Help!

Hi!

I've used my hackintosh comptuer for a while now (yes I know this is the wrong place to talk about hackintoshes lol, but I thought I'd give it a shot, as I own other apple computers such as an iMac, Macbook Pro, Ipad, iphone etc. And also this gorgeus Apple Cinema 27" Display.

I have a 27" DELL screen connected already, which works like a charm (using a DVI-D cable).

But now I bought a new screen (an Apple Cinema Display 27"), and I bought an adapter from minidisplayport to displayport which goes into my graphics card.

Specs of computer:

Asus Sabertooth x79 motherboard

GeForce GTX 660

Intel 3930k processor

etc.

I get absolutely NO signal what so ever to my apple cinema display 27" which is connected to the displayport input of my graphicscard. But I tried to connect the Cinema Display to my Macbook pro and it works absolutely fine.

I read something about UEFI problems with displayport/cinema displays

but is there a fix for it? I really need to get my brand new cinema display to work with my hackintosh! It was expensive as **** aswell.

please, someone help me. I would so much appreciate the answers.

Thanks alot!

Best,

J
